Yangzhou City in Jiangsu Province, the municipal government issued a notice of 2019 annual remediation tasks boiler water treatment, with the text published a list of boiler regulation, as follows.

3, the nitrogen gas boiler oxide (NOx) emission limit is not higher than 50 mg / m transformation, in accordance with other indicators of "boiler air emission standards" in the gas-fired boiler particularly performed emission limits.

(1) prohibits blended with other fuels such as coal, bags and other supporting efficient dust removal facilities, and effectively discharge standards. Emission standards in accordance with "boiler air emission standards" in coal-fired boilers particularly performed emission limits.

Full implementation of the above steam 2,65 t / h coal-fired boiler transformation ultra-low emission, soot, sulfur dioxide, nitrogen oxides, respectively, 10 mg / m, 35 mg / m, 50 mg / cubic meter.

3, disable all kinds of close small coal-fired facilities (tea boiler and furnace operating coal-fired stove, rural production, aquaculture and other coal-fired facilities), switching to natural gas, electricity, solar and other clean energy. In remote rural areas, could be replaced by forming biomass as a fuel, but must use a professional boiler, supporting efficient dust removal facilities, to ensure that pollutant discharge standards, emissions standards refer to "boiler air pollutant emission standards" in particular coal-fired boiler emission limits carried out.

4, a low nitrogen gas boiler and treatment for the transformation, the installation of low NOx combustion by the low NOx combustion mode, etc., to ensure that the nitrogen oxide emission limit is not higher than 50 mg / m. Other indicators according to "boiler air emission standards" in the gas-fired boiler particularly performed emission limits.

5, forming a comprehensive remediation biomass fuel boilers, biomass fired boiler clean-up does not meet the special requirements of the boiler, not supporting a biomass fired boiler emissions and efficient dust removal facilities of non-compliance. To meet the special requirements of the boiler and supporting efficient dust removal facilities, the establishment of accounting and retain more than one year, emission standards refer to "boiler air pollutant emission standards" emission limits in particular the implementation of coal-fired boilers. More than 10 tons of steam installation of gas-line monitoring instruments, and networking with the environmental protection department. Located in the city built-up area forming ultra-low emission biomass boilers implement reform.

6, bulk coal sales within the city limits are all clear according to the law, the use of bulk coal user implementation of the "coal to electricity" for street vendors and other "coal to gas" campaign, a pin number management. At the same time, prohibiting the establishment of long-term supervision mechanism bulk coal, non-bulk coal inflows.

More economical steam boiler water treatment can play a role in energy saving produced by the steam boiler is high-pressure gaseous, during use, a large amount of steam can be generated, so the use of the pressure vessel, in which a related aspect there is a certain provisions, whether used or installed must comply with some aspects, and apply the relevant evidence, but also to accept the annual inspection. This boiler used in the printing and medical care more. If the hot water boiler is produced, so it is not pressurized container, are often used in our lives, is relatively small in terms of investment, use of the process, management costs are very low, of course, will be more secure. Some schools or community-related, may also be related to the use of this method of heating water, relatively speaking, it will be more convenient. Steam boiler in the structure, allowing fuel to burn more fully, and in the process run more stable, can really improve efficiency, which would allow users to better reduce costs, the whole of it will be more use more protection. Many places are in use, can play a role in energy saving, and relatively more economical, so that it can use real protection. From the analysis of the specific works, the use of the process, the main heating device to release heat, then by a certain conversion, a large amount of steam, and the steam trap correlate. Use of the process, increasing the temperature of the steam is then able to reach the required temperature. This works, this works can improve work efficiency, and truly play a better role. Structure and principles of steam boilers, this area will affect the future use, advance the understanding of the relevant circumstances are, and have the knowledge of the whole of use, which for us will have more benefits, so be sure to do ahead of time to consider. Before purchasing equipment, we have to confirm in advance that these circumstances device, so that it can ensure that the specific choice of fruit, you can also make use of the process more smoothly. Different devices are not the same in construction and principle, let me use the process, there will be different results. Structure and principles of steam boilers is what, to correctly do know these aspects, then the future in the selection process, will have a corresponding basis for these people to purchase provides choice, so we have to advance to do a good understanding.

Ordinary nitrogen oxide emissions from gas-fired boiler water treatments up to 150-200 mg / cubic meter high, in recent years, China's environmental protection department has gradually been prohibited burning or low-nitrogen transformation process. Nitrogen gas boiler is low by use of the premix, of FGR flue gas recirculation and other advanced technology for low NOX combustion, greatly reduced emissions of nitrogen oxides. Fast boiler now available low nitrogen condensing gas boiler below 20 mg / cubic meter for our most stringent environmental standards such as Beijing, Xi'an, Zhengzhou and other cities (standard of 30 mg / cubic meter).

Feedwater temperature decreases, the steam temperature rise but why? In order to improve the thermal efficiency of the entire power plant boiler water treatment, power plant boiler feedwater heaters are equipped, the heater previously called feed pump low pressure heater, after giving the high-pressure pump called the Heater. By high pressure feedwater heaters, water temperature greatly increased. For example, medium pressure feed water temperature of the boiler mostly heated to 172 deg.] C, typically heated to a high pressure furnace 215 ℃.
